MOTOR.

Application filed December 16, 19.25. Serial No. 75,735.

- invention relates to improvements in water or fluid motors and more especially to such a motoradapted foruse in connection 'withy aA mechanical tooth brush.,

One .ofthe featuresof my invention is the making of such a motor which is simple and cheap l yconstruction and yet serviceable and durable.

Another important feature of the invention is the making of such a motor which is reversible. This is especially desirable in a motor to be used with a tooth brush as such a device is more eective when the action is reversed occasionally than when the action is constantly in one direction.- The reversing of the motor is very easily accomplished without requiring diflicult adjustments.

Other features and advantages of my in? vention will appear more fully as I proceed with my specification.

In that form of device embodying the features of my invention, shown in the accompanying drawings, Figure 1 is a vertical sectional view of the motor showing the same in use as a tooth brush, Fig. 2 is a view taken as indicated by the line 2 ofrFig. 1; Fig. 3 is a view taken as indicated by the line 3 of Fig. 1; and Fig. 4 is a view in side elevation of the same.

As shown in the drawings, the device comprises a substantially cylindrical casing 10 provided with a water inlet nipple 11 to which a water supply tube 42 is attached in the usual manner. The lower end of the casing 10 as indicated by 10a is open and permits the discharge of water. The upper end of the casing 10 is closed as indicated by 10b with the exception of a small central opening through which projects the hollow rotor shaft 12 which carries the brush 13. The brush 13 is provided with a shank 14 adapted to be inserted in the end of the rotor shaft 12 and held therein by frictional engagement.

The lower bearing for the rotor shaft 12 is formed by the upper end of a screw 15 which is threaded through the transversely arranged tube 16 which is held in place in the casing 10 by means of the two screws: 17, 17. The screw 15 is held in position by the lock nuts 18, 18. The lower end of the screw 15 is further held in position by means of the wire 19 which is twisted a few times around the lower end of the screw and thence carried over to the walls of the casing 1() and thence bent downwardly as'indicated by 19a. This wire is .preferably arranged at right angles to the tube `16 in orderto prevent rotation thereof on the screws 17.l The upper end of they screw 15 carries,a"block 20'forined with a slight concavi-ty in 'itsuppersurface in which rests 4theli'lo'lwer:,end o f the pin 21 which is inserted inthe rotor'shaft 12 in order to form a bearing therefor.

The rotor shaft 12 carries a rotor wheel 22 here shown as provided with six vanes 23 adapted to ybe engaged by the incoming stream of water and rotated thereby.

l/Vhere the nipple 11 enters the casing 10 there is provided a pivoted valve plate 24, pivoted on the wire 25 at one edge. The valve plate 24 is adapted to take either one of two positions as shown in Fig. 2, one of the positions being indicated by the solid lines and the other by the broken lines in this figure.

It will be seen that the valve plate 24 will operate to deflect the stream of water enter- In the operation of the device, the water is turned on and the pressure vof water will drive the valve plate 24 to one side or to the other, giving a certain direction of rotation to the motor. In the event it is desired to reverse the rotation of the motor, the water is momentarily turned oil and the motor laid over on one side slightly, in order to cause the valve plate 24 to fall to the opposite side from this last position. The water is again turned on and the flow of water will hold the valve to the side, and the direction of rotation of the motor will be changed. In this manner it is possible to reverse the direction of rotation of the motor as frequently as desired.

It will be seen that the shape of the casing for the motor especially adapts it for use as a tooth brush. By having the rotor shaft projecting from the upper closed end of the cylindrical casing, the same may be easily inserted in the mouth of a user while leaning over a washbowl.- WhenV thus in use, the water escapes from the lower open end of the cylindrical casing into the washbowl.

The casing being cylindrical is easily held in the hand and thus is suitable as a handle for the motor.

While I have shown and described certain embodiments of my invention, it is to be understood that it is capable of many modications. Changes, therefore, in the construction and arrangement may be made without departing from the spirit and scopey of the invention as disclosed in the appended claim, in which it is my intention to claim all novelty inherent in my invention as broadly as 'possible in view of the prior art.

What I claim as new, and desire to secure by Letters Patent, is:

In a device of the character described, a substantially cylindrical casing constituting a handle, said casing being open at the bottom and closed at the top, a shaft in said casing to operate a tool, a rotor on said shaft, a water inlet nipple on said casing, and a loosely pivoted valve in said nipple for directing water which enters the casing from the nipple in a direction tangential to either side of the rotor whereby said water entering the casing through said nipple operates the rotor and its shaft and escapes through the lower end of said casing, the shifting of said valve being controlled through the tilting of said casing.Y

In testimony whereof, I have hereunto set my hand this 8th day of'December', 1925.
